BOB: a Basic On-line Ballot-box

First things first. Electronic voting is a thorny topic, and
unavoidably so. Please think very carefully about the risks involved,
and definitely do not assume that I've done so for you.

The BOB system is designed to be an electronic version of a ballot
box for Single Transferable Voting elections.
The original BOB distribution only provided a means to collect ballots, but the system has been
significantly extended by other developers, in particular Martin Lucas-Smith.

To ease its subsequent development, the project is now hosted at Github, however the complete BOB project page as it was prior to the Github shift, and its linked release versions (good, bad and/or ugly) remains available as an archive.

Notes

The BOB system is intended to be used in a context where people
will verify that their votes were recorded correctly after the ballot:
thus the software itself cannot cause an undetectable manipulation of
the election's result (although this approach introduces other
potential problems, such as provable vote selling).

I hope this software might be useful to you, but as the GPL says,
this code doesn't come with any warranties! None of the people
involved with writing, testing or checking this code have been
contracted to do so. While I would be very pleased to know that it is
assisting larger organisations' elections, the code was not originally
written with that target in mind. Of course, I haven't set out to
write a completely broken system either!

Credits

Most of the core electronic voting system
code was written by me
(David Eyers). However the extra checks and
balances, administration, configuration and installation support
written by others now completely eclipse the core voting system in terms of lines
of code.
